mbldr

mbldr (Master Boot LoaDeR) is a boot loader which
fits into the first sector of an HDD (MBR). It
allows the user to choose which partition to boot and is intended to replace an MBR that comes with DOS/Windows (fdisk /mbr). It may boot OSes above the 1024th cylinder, and Linux and BSD are also supported. mbldr is based on OS Boot Select (OS-BS) project by Thomas wolfRAM.
